patterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولNoninvasive imaging of left coronary arteriovenous fistula.
We investigated a patient with coronary arteriovenous fistula (CAVF) by two-dimensional echocardiography (2-DE), cardiac Doppler, cardiac catheterization and nuclear magnetic resonance (NMR). These investigations clearly showed the abnormal vascular structures. NMR is another valuable noninvasive and safe method of confirming the presence of a CAVF.
متن کاملValidation of 3D power Doppler and VOCAL software in the sonographic assessment of hepatic venous flow
UNLABELLED AIM To evaluate the reproducibility of three-dimensional power Doppler ultrasonography (3D-PDU) and the repeatability of Virtual Organ Computer-aided AnaLysis (VOCAL) software in the assessment of hepatic venous flow in ten healthy non-pregnant individuals. METHODS Visualization of hepatic veins was performed using both intra- and subhepatic approaches; These examinations were ...
متن کاملA comparison of Power Doppler with conventional sonographic imaging for the evaluation of renal artery stenosis
BACKGROUND Power Doppler (PD) has improved diagnostic capabilities of vascular sonography, mainly because it is independent from the angle of insonation. We evaluated this technique in a prospective comparison with conventional imaging, consisting in Duplex and Color Doppler, for the evaluation of Renal Artery (RA) stenosis. METHODS Sensitivity, specificity and predictive values of PD and con...
متن کاملSpinal dural arteriovenous fistula : a case report
Background: Spinal dural AVF is the most common type of spinal vascular malformation. However, presenting symptoms differ according to site of spinal involvement. This study described a case of arteriovenous malformation with paraparesis and incontinence. Case Presentation: Diagnosis of patient was confirmed by clinical and imaging examination using magnetic resonance image and ruling out ot...
